RCA P52921 changed channels by itself and I unplugged it to reset it and it did the same thing a few minutes later. Unplugged it again and now it won't come on at all.

    OK, hubby got the tv to come back on by checking a board that has the #'s 1518844D. TV won't change channels by remote but will by the controls on the tv's front. Could this board be the problem and if so where can I buy one.
    Thanks

    rca projection t model p52921.

    Started changing channels on the screen (numbers only not the channels themselves). Unplugged it and turned it back on and it did it again after a couple of minutes. Then unplugged it and wouldn't come back on. Finally got it back on today after checking circuit board with 1518844D on it, while checking this board it came back on. Won't work with remote, and sometimes works with controls on front of tv, but sometimes menu won't go off and controls on front of tv won't do anything. Remote control won't work at all, with new batteries installed. #'s for channels still changing on screen. I hope I put it in words that everyone can understand what I mean is happening to it.

    Where can I buy the tact switches? I have already put so much money in this tv for repair after repair that I don't want to put much more. If they aren't much I will replace them myself. Really appreciate the help.

Buy a control to see if there is a problem with your control.

Take batteries off the remote and check if it is the remote , otherwise it is a stuck key on the tv or the control board is gone,

    If it does not come up at all it may be the PSU that was starting to fry up, that may be reason why your tv started doing funny things.
    However, it is possible that the PSU is fine and just some other part have blown.
    You should also test or have tested from a service centre, the DTV board, which is the main board inside the tv, that may had been damaged.

    Test and eventually change the control board. #1518844D is the audio/video IO board. If you had problem with that usually your audio or video has problems.

    You can also try to do a diagnosic, I have the following general procedure, it works on most RCA tvs :

    GE TELEVISIONS / RCA TELEVISIONS / PROSCAN TELEVISIONS

    Read the _ SERVICE MODE WARNING _ before proceeding.


    To enter service mode, push and hold the [Menu] button on the set.
    While holding, push and release the [Power] button, then the [Vol +]
    button.


    You will now have some information on the screen: "P0 V0"


    To actually be able to change these values, you must push [Vol +] on
    the remote so the information reads V76. Then pushing on the Channel
    +/- will change the "P" value.


    P1 - 3 are error codes. If there is a problem with the set that can be
    self-diagnosed, the "V" will report the code. These codes are available
    in the RCA repair manual.

    P4 - 7 control the horizontal size, shift, vertical size and shift.


    You may also find a summary leaflet for the service tech clipped
    somewhere inside the chassis. The procedures for getting into the
    service mode, as well as the service items of interest will be there.

TV keeps changing channels


Out of 30 years in the repair field, I have seen this problem maybe 4 times. Once was a stuck button on the keypad of the tv. The other time was a second remote control with a book sitting on it and it would turn the tv on and off when someone would move something on the coffee table, another time was a bad solder connections on the microprocessor on the keypad circuit board and the last time was from a humorous neighbor in an apartment complex who thought he was funny who had an all in one remote control programmed for his neighbor's tv set.

You will need to connect your antenna and do an auto search. When the search is over you might have to choose the broadcast option over the cable selection. That might bring in the picture.

Big mistake

If you can find the horizontal output transistor which is located near the flyback transformer,one lead of this drive transformer is connected to the base lead. (horizontal output transistor). There may be a little coil in series with this lead going to the transistor.
